Gemma 4: The Local LLM That's Actually Worth Running (And Where It Falls Short)

Short summary

Gemma 4 is the best open-source local LLM available but fails to match marketing promises. Mixture-of-Experts activation (3.8B of 26B total) limits reasoning depth by 10-20% vs true 26B models, multimodal inputs add overhead, and long context incurs speed/memory costs. Use Gemma for privacy, cost-at-scale, or sub-100ms latency requirements; Claude and GPT-4o offer superior reasoning.

• •MoE design activates only 3.8B of 26B parameters, underperforming dense models by 10-20% on complex reasoning tasks
• •Multimodality and 256K context add overhead and memory costs not highlighted in marketing materials
• •Best for privacy-critical, cost-sensitive, or ultra-low-latency use cases; Claude/GPT-4o deliver better reasoning quality
